CRUSI-IING Application iled February 17, 1925, Serial No.

rIhe presentinvention relates to machines or apparatus for refining pastes, liquids and semi-liquids, such as chocolate, paints, and the like, wherein the refining is accomplished by a grinding or crushing action between a roll or rotary device and a bed.

1t is an obj ect of the invention to provide a refining machine comprising a cooperable roll and bed wherein the cooperable grinding or crushing surfaces' of the roll and bed are of novel formation and construction in order to increase the eHiciency and capacity of the machine.

Another object of the invention is the provision of a roll and bed construction by means of which the material to be refined is caught under the roll and more effectively dealt .with as compared with a plain roll working on a flat or smooth bed.

With the foregoing and other objects in view, which will be apparent as the descrip tion proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made Within the scope of what is claimed, Without de parting from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a view, partly in side elevation and partly in section, of a roll and bed embodying the improvements.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Figs. 3 ande are views similar to Fig. 1 illustrating modifications. Y

Fig. 5 isa plan view illustrating` still another modification.

Fig. 6 is a vertical section on the line 6-6 of Fig. 5,

.Referring to Figs. 1 and 2. there is shown therein a roll 10 working on a bed 11, and, in carrying out the invention, the roll has a periphery composed of rods or members 12 of cylindrical form and disposed in an annular series with their axes parallel to the axis of the roll. The roll and crushing or grinding members 12 thereof may be of any desired size. The bed 11 includes a rack 13 having transverse concaved grooves 111 in the upper surface thereof into which the members 12 can fit snugly, said grooves being curved to correspond to the peripheries of said members 12. Asshown, the rack 13 is set in a channel 15 of a container MACHINE.

or vessel 16 which holds the material to be refined, in order that such material will flow or run into the grooves 14: under the roll. As shown, the bed 11 is straight for relative rectilinear movement between the bed and roll, and the rolling action is either obtained by the movement of the roll back and forth over the bed, or by the reciprocation of the bed under the roll, the members 12 engaging in the grooves 14 similar to the engagement of the teeth of a gear pinion with the teeth of a gear rack.

ln the embodiment as shown, the roll 11 is composed of a body 17 and side plates 18, said plates being of slightly larger diameter than the body to project beyond the periphery of thebody. The periphery of the body has tran, verse grooves 19 in which the members 12 are seated,y and said members have the square or non-circular lugs 2O at their encs seated in similarly shaped apertures 21 in the plates 18, thereby holding the members 12 assembled with the body 17 in a substantial and rigid manner. The edge portions of the plates 18 also provide annular fianges to overlap the opposite edges of the racl; 13 to assist in conning the material between the roll and rack. The body 17 is of a dimension longitudinally of its axis equal to the length of the members 12, so, that` said members inv seating in the grooves 19 may be subjected to considerable pressure without springing or yielding. Furthermore, the body 17, conceals the inner portions of the vmembers 12, so that only the outer portions thereof are exposed, thus preventing the material from getting behind said members 12.` rEhe ridges or ribs on the periphery of the body 17 between the grooves 19 extend between the members 12, thereby bracing said members against springing oryielding movement toward one another, as well as closing the spaces or slots between saidmembers. By separating' the side plates 18, the members 12 are loosened in order that they may be turned about their axes to different positions, thereby increasing the life of said members, inasmuch when the exposed surfaces thereof have been worn said members may be adjusted to present the othersurfaces thereof to engage the bed.

`When the rolling action between the roll and bed occurs the rods or members 12 move into and out of the grooves 14 and'have partial turning movements in said grooves, thereby increasing the effective grinding surfaces between the roll and bed for any given diameter of roll. Furthermore, the material is caught in the grooves 14 under the roll so as to be given an eifective crushing or grinding action between the convened or cylindrical surfaces of the members 12 and the concaved surfaces of the grooves 14. rlhis will avoid the'material being washed or carried away from between the roll and bed, as occurs between a plain roll and a smooth or flat bed, inasmuch as the material "in the grooves 14 will remain therein E as the members 12V move down into the grooves.

lThe same action occurs if the roli has a complete or only a partial rotation.

As shown in Fig. 8 the bed 11 can be v curved with the roll on the concaved top surface thereof, and said bed may constitute the rim of a rotary ydrum or wheel. Fig. 4 shows theroll working on a bed which is convened, and such bed may be the rim or periphery of a drum or wheel with the roll 10 working on the top thereof.

The bed may also be of annular form to rotate about a vertical anis, orto permit the roll to roll on the bed along acircular path. Thus, as shown in Figs. 5 and 6 the bed 11 constitutes a wheel rotatable about a vertical axis, and the rack 13 is of annular form, being Aset in an annular channel 15 of a rotatable container or vessel 16. The roll 10 and rack 13 engage one another similar to bevel gears, whereby they can rotate about horizontal and vertical axes, respectively. The roll 10 is of conical form, the members 1Q and grooves 14 being tapered soy as to fit together snugly as the roll and rackhave rolling contact.
